Putting it in your hair and combing it through wont work well. Ive found through trial and error that if i get out of the shower and towel dry my hair , i can part the hair and apply Couvre starting at the top and working my way down to the forhead (as not to have a glob at the hair line). I then wait for it to dry (5 to 7 minutes is usually adequate) and then apply Toppik.
Hope this helps.
